4 Claims. (01. 300-21) This invention relates to a treated paint brushand to a process for preparing a treated paint brush and has for anobject to provide an improved process of preparing a paint brush and 5to provide an improved treated paint brush.

A further object of this invention is to prcvide a treated paint brushwhich need not be broken in but which is ready for immediate use withoutany further preparation by the purchaser.

With the foregoing and other objects in view, as will hereinafter becomeapparent, this invention comprises the constructions, combinations andarrangements of parts, hereinafter set forth, disclosed and shown on theaccompanying drawmg.

In the drawing,

After the brush 10 is taken from the linseed oi1 12 it is then washed inwarm soapsuds 13 of imported castile soap, which has a base of oliveoil. After being so washed the bristles 11 are then rubbed or cleanedagainst sandstone, or other abrasive surface, thereby removing all sur-40 plus linseed oil not absorbed in the cells of the bristles. Thisleaves the bristles clean and straight for rubbing the bristles 11 ofthe brush 10 on sandstone or other abrasive surface serves to break inthe brush. That is rubbing the brush on a sandstone or other abrasivesurface wearing down the end of the brush to a slight taper, therebyproducing a broken in new brush. Sandstones because of their roughnesspermit the wearing down procedure to result faster, although it canlikewise be done on an ordinary washboard or any other suitable abrasivesurface. The bristles 11 are next wrapped in absorbent paper 14 whichabsorbent paper may be old newspaper or the like. This serves the doublepurpose of absorbing the excess moisture in the brush and at the sametime of giving the bristles of the brush their proper form or shape.

After being wrapped in the absorbent paper 14 it is then placed in aslow heated oven 15 over a period of twenty-four hours, during whichtime the moisture is evaporated and a perfect prepared working tool iscompleted. A treated paint brush thus prepared according to theforegoing process saves the painter time in preparing such a brush forhimself, eliminating the necessity of the painter breaking in the brush.The treated brush will in all cases have the preparedness necessary fora brush to function perfectly, thus enabling the ordinary, unskilledpurchaser to have a perfect brush at his disposal on purchas- 7o ing thesame without being under the necessity of attempting to himself preparethe brush for use.

This process of treating the brush eliminates all dirt, dust andunwanted substances in the bristles, thus enabling the brush tofunctionperfectly in operation.

The novel features and the operation of this. device will be apparentfrom the foregoing description. While the device has been shown and sothe structure described in detail, it is obvious that this is not to beconsidered limited to the exact form disclosed and that changes may bemade therein within the scope of what is claimed without departing fromthe spirit of the invention.

Having thus set forth and disclosed the nature of this invention, whatis claimed is:

1. Ihe process of preparing a paint brush comprising the step of causingthe cells of the paint brush bristles to absorb linseed oil, washing theno bristles in warm castile soap suds, cleaning the bristles againstsandstone, wrapping the bristles in absorbent material to absorbmoisture therefrom and shape the bristles, and exposing the bristleswhile so wrapped to a slow heat for a period of time to evaporate themoisture and perfect the brush.

2. The process of preparing a treated paint brush comprising the step ofplacing the bristle end of the paint brush in raw linseed oil over aperiod of approximately one half a day, then washing the bristles inwarm castile soap suds, then rubbing the bristles on sandstone, thenwrapping the bristles in absorbent paper to shape the bristles andabsorb the moisture therefrom 0 and then exposing the bristles while sowrapped in a slow heated oven-over a period of approximately a day toevaporate the moisture and perfeet the brush.

3. The process of preparing a paint brush comend of the paint brush inraw linseed oil over a period of approximately one half a day, thenwashing the bristles in warm castile soap suds, then rubbing thebristles on an abrasive surface, then wrapping the bristles in anabsorbent material to shape the bristles and absorb the moisturetherefrom and then exposing the bristles while so wrapped in a slowheated oven over a period of approximately a day to evaporate themoisture and perfect the brush.
